ANJOSHI Circuit Breaker 150Amp 50A-300A: Manual Reset Home Solar System Fuse Holder for Car Audio & Amps Protection - 12V-24V DC Reset Fuse Inverter | Replace Fuses Efficiently Review

I bought 15 Anjoshi (based on good customer reviews from Revain). Seven failed within a day or 2 months of starting use. A 100A circuit breaker has tripped at a constant 50A load for 3 minutes. One of the clamps gets too hot to touch. Replaced with a 200A circuit breaker, same 50A continuous load, works in 5 minutes. Replaced by a device from the Bussmann 285 series, 100A device, same 50A continuous load, everything OK, terminal barely warm.

I installed this circuit breaker. worked 3 hours. Then I turned it on and off several times while I worked on the wiring. After that, it returned to the reset position, but didn't run again. After playing around with it for a while, I ordered a new breaker. I disassembled the old switch and it was stuck inside. Luckily it was cheap. I don't know, maybe I was just unlucky, but I ordered a different brand to be on the safe side.

So I used mine as a switch and breaker. I put it on a 72v 3000w 45 AE bike and it has never been dropped so I have no idea if it will work when needed. All I knew was that it was a very handy main switch that could handle 50 amps. It has worked great until now when it no longer has pole-to-pole conductivity. If you hit it right and really hit the multimeter's pins, it will unpredictably jump from 1 million ohms to 500 kohms and only sporadically to a few ohms. The only reason I noticed this is…
